Management of a Dentigerous Cyst Associated with Mesiodens: A Case Report

Abstract

1. Introduction Supernumerary tooth is defined as a developmental anomaly characterized by the presence of an extra tooth in addition to the normal dentition [1] . It can affect both maxilla and mandible; however, its occurrence in the mandible is rare [2] . While supernumerary tooth may be found in any region of the dental arch, the most common site is the palatal midline between the two maxillary central incisors, where it is termed as mesiodens [3] . Mesiodens is the most common type of supernumerary tooth which may appear as single, multiple, unilateral or bilateral. It accounts for 80% of all supernumerary teeth [3] .A mesiodens may erupt normally, stay impacted, appear inverted or take a horizontal position [3] .Unerupted mesiodens can be diagnosed by both clinical and radiographic evaluation, which can be done bypanoramic, maxillary occlusal and periapical radiographs are recommended [1] . Supernumerary tooth if left undiagnosed leads to many complications; most common one is dentigerous cyst and radicular resorption. Dentigerous cyst typically originates due to fluid accumulation between reduced enamel epithelium and the developing crown of the tooth, causing expansion of the tooth follicle & is typically attached to the cervical area of the tooth [4] . This case report presents a mesiodens associated with dentigerous cyst.
